OpenAI updates privacy policy to share user data with advertisers
OpenAI has updated its privacy policy, effective 30 April 2026, to allow the sharing of user data with advertisers. The change lands as ChatGPT uninstalls have surged, and as OpenAI is in court with Elon Musk over allegations that the company has abandoned its founding principles.
What changed
Trishla Ostwal has surfaced the privacy policy update.
The advertising-relevant cut is what the data sharing enables. Combined with Juozas Kaziukėnas' separate finding that the OpenAI conversion-tracking pixel now accepts hashed first-party data: email, location, IP, browser version: the architecture for cookieless attribution and AI-driven targeting on ChatGPT inventory is materially more capable than it was a quarter ago. Meta and Google have used the same hashed-data workaround for years; OpenAI is now operating on the same playbook.
Why it matters for advertisers
For you, this means ChatGPT advertising is rapidly converging with mainstream paid search and paid social attribution capabilities. Worth re-baselining any planning that treats ChatGPT inventory as awareness-only: the targeting and attribution infrastructure for performance buying is now functionally in place. Particularly relevant for advertisers with privacy-sensitive customers, where the privacy policy change may trigger reputational or contractual review.
